|
||
|
|
|
||
|
|
|
||
|
|
The QGfxDriverPlugin class provides an abstract base for
|
||
|
|
Qt/Embedded graphics driver plugins.
|
||
|
|
<p>
|
||
|
|
<p> The graphics driver plugin is a simple plugin interface that makes
|
||
|
|
it easy to create custom graphics drivers.
|
||
|
|
<p> Writing a graphics driver plugin is achieved by subclassing this
|
||
|
|
base class, reimplementing the pure virtual functions <a href="#keys">keys</a>() and
|
||
|
|
<a href="#create">create</a>(), and exporting the class with the <tt>Q_EXPORT_PLUGIN</tt>
|
||
|
|
macro. See the <a href="plugins-howto.html">Plugins
|
||
|
|
documentation</a> for details.
|
||
|
|
<p> This class is only available in Qt/Embedded.
|
||
|
|
<p>See also <a href="plugins.html">Plugins</a>.

|
||
|
|
<h3 class=fn><a name="QGfxDriverPlugin"></a>QGfxDriverPlugin::QGfxDriverPlugin ()
|
||
|
|
</h3>
|
||
|
|
Constructs a graphics driver plugin. This is invoked automatically
|
||
|
|
by the <tt>Q_EXPORT_PLUGIN</tt> macro.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="~QGfxDriverPlugin"></a>QGfxDriverPlugin::~QGfxDriverPlugin ()
|
||
|
|
</h3>
|
||
|
|
Destroys the graphics driver plugin.
|
||
|
|
<p> You never have to call this explicitly. Qt destroys a plugin
|
||
|
|
automatically when it is no longer used.
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qscreen.html">QScreen</a> * <a name="create"></a>QGfxDriverPlugin::create ( const <a href="qstring.html">QString</a> & driver, int displayId )<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> Creates a driver matching the type specified by <em>driver</em>, that
|
||
|
|
will use display <em>displayId</em>.
|
||
|
|
<p> <p>See also <a href="#keys">keys</a>().
|
||
|
|
|
||
|
|
<h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="keys"></a>QGfxDriverPlugin::keys () const<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> Returns the list of graphics drivers this plugin supports.
